ios 设置状态栏背景颜色

第一种方法:

[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleBlackOpaque;

self.navigationController.navigationBar.tintColor = [UIColor blackColor];

if (is_ios_7_Later) {

self.view.window.frame = CGRectMake(0, 20, self.view.window.frame.size.width, self.view.window.frame.size.height - 20);

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent animated:NO];

}

第二种方法(这方法比较简单):

UIView *statusBarView=[[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 20)];

statusBarView.backgroundColor=[UIColor blackColor];

[self.view addSubview:statusBarView];

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:NO];
